We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).

"The Raspberry Piproject relies heavily on Open Source and Free Software — heck, it's targeted by more than one Linux distro. But some of the hardware stack that makes up the Pi itself needs closed-source code to run; the code that runs all kinds of low-level hardware is often closed source and closed off. I got wind from project instigator and lead Eben Upton that the system-on-a-chip at the Raspberry Pi's heart is about to get a lot more open. Says Upton: "We're about to open source all of the remaining closed source ARM code for the Pi. This will make BCM2835 the first ARM multimedia SoC with a fully-open-source ARM user and kernel implementation." I spoke for a few minutes with Alex Bradbury, who runs the Linux software work for the project, about licensing and what the new code means not only for Raspberry Pi but for users and other OS projects." (Note: the sound quality on this translantic Skype call is poor. We suggest reading the transcript.) Get the code while it's hot.

An anonymous reader writes "After being talked about for four years, Wayland 1.0 was released today. The Wayland 1.0 release doesn't mark it yet as being ready for Linux desktop usage but just being API/protocol stable for future expansion. Wayland will now maintain backwards compatibility going forward, but how much longer will it take to replace X11 on the Linux desktop? Quite a while seems likely."

madsdyd writes "I am a long-time user of Linux (since 1997) and have not been using Windows since 1998. All PCs at home (mine, wife's, kids') run Linux. I work professionally as a software developer with Linux, but the Windows installs at my workplace are quite limited, so my current/working knowledge of Windows is almost nil. At home we have all been happy with this arrangement, and the kids have been using their Nintendos, PS2/3's and mobile phones up until now. However, my oldest kid (12) now wants to play World of Warcraft and League of Legends with his friends. I have spent more hours than I like to admit getting this to work with Wine, with limited success — seems to always fail at the last moment. I considered an Apple machine, but they seem to be quite expensive.
So, I am going to bite the bullet, and install Windows 7 on a spare Lenovo T400 laptop, which I estimate will be able to run both Windows 7 and the games in question." Read on for more about the questions this raises, for someone who wants to ensure that a game-focused machine stays secure.

sfcrazy writes "While the larger Ubuntu community was busy downloading, installing and enjoying the latest edition of Ubuntu yesterday, a post by Ubuntu founder Mark Shuttleworth ruffled some feathers. He gave the impression that from now on only select members of the community will be involved in some development and it will be announced publicly only after completion. There was some criticism of this move, and Shuttleworth responded that they are actually opening up projects being developed internally by Canonical employees instead of closing currently open projects. He also made a new blog post clarifying his previous comments: 'What I offered to do, yesterday, spontaneously, is to invite members of the community in to the things we are working on as personal projects, before we are ready to share them. This would mean that there was even less of Ubuntu that was NOT shaped and polished by folk other than Canonical – a move that one would think would be well received. This would make Canonical even more transparent.'"

An anonymous reader writes "The six month cycle that Canonical adheres to for Ubuntu releases has come around again today. Ubuntu 12.10 'Quantal Quetzal' has been released. There's a whole range of new features and updates, but here are the most important: WebApps — treats online services as if they are desktop apps (Gmail, Twitter, Facebook); Online Services — control logins to all your services from a single window and get them integrated into search results (e.g. GDocs for file searches); Dash Preview — right click any icon, get a detailed preview of what it is; Linux kernel 3.5.4; GNOME 3.6; Nautilus 3.4; latest Unity; No more Unity 2D, fallback is the Gallium llvmpipe software rasterizer; Default apps updated (Firefox 16.01, Thunderbird 16.01, LibreOffice 3.6.2, Totem, Shotwell, Rythmbox); Full disc encryption available during install; Single, 800MB distribution for all architectures." It's now available for download. The next version, due in six months' time, will be called Raring Ringtail.

An anonymous reader writes "During the 12th Annual Global LambdaGrid Workshop in Chicago, researchers have demonstrated interactive multi-point streaming of 8K/UHDTV (i.e., 16x Full HD resolution) using commodity PC hardware running Linux and open-source UltraGridsoftware. The transmissions featured GPU-accelerated JPEG and DXT compressions implemented using the NVIDIA CUDA platform, which are also available as open-source software. The streams were distributed from the source to one location in the USA and to another location in the Czech Republic over 10Gbps GLIF network infrastructure."

jrepin writes "KDE has released the 3rd stable version of Plasma Active, KDE's device-independent user experience. The Plasma Active user interface is touch-friendly and works well across a range of devices. Its Activities function gives users a natural way to organize and access their applications, files and information. Plasma Active Three noticeably improves the user experience with its enhanced and expanded set of apps, improved performance and a new virtual keyboard."

gManZboy writes "If you skip Windows 8, you lose the appealing opportunity to synchronize all of your devices on a single platform — or so goes the argument. If you're skeptical, you're not alone. OS monogamy may be in Apple's interest, and Microsoft's, but ask why it's in your interest. Can Microsoft convince the skeptics? 'If the hardware and software are the same at home and at work, one can't be "better" than the other. It would help if Microsoft convinced users like me that their platform is so good, we'd be fools to go anywhere else,' writes Kevin Casey."

An anonymous reader writes "TaskuMuro, a Finnish tech news site, has anonymously interviewed various Nokia employees and pieced together an interesting timeline of the events which led to the abandonment of the Nokia MeeGo platform and to Nokia's current affiliation with Microsoft and Windows Phone. It appears the MeeGo project was rather disorganized from the get-go and fell victim to the company's internal tug-of-war, aimless management causing several UI redesigns and a none-too-wise reliance on Intel components which lacked some key features – namely, LTE support."

Ever since news broke last year that Microsoft would require Windows 8 machines to have UEFI secure boot enabled, there were concerns that it would be used to block the installation of other operating systems, such as Linux distributions. Now, reader dgharmon sends this quote from Ars Technica about a new defense against that outcome:
"The Linux Foundation has announced plans to provide a general purpose solution suitable for use by Linux and other non-Microsoft operating systems. The group has produced a minimal bootloader that won't boot any operating system directly. Instead, it will transfer control to any other bootloader — signed or unsigned — so that can boot an operating system."
The announcement adds, "The pre-bootloader will employ a 'present user'; test to ensure that it cannot be used as a vector for any type of UEFI malware to target secure systems. This pre-bootloader can be used either to boot a CD/DVD installer or LiveCD distribution or even boot an installed operating system in secure mode for any distribution that chooses to use it."

DMA-BUF is a recent kernel feature that allows multiple GPUs to quickly copy data into each others' framebuffers. A use case would be the NVIDIA Optimus that pairs a fast GPU with an Intel integrated GPU, where the NVIDIA GPU writes into the Intel framebuffer when it is active. But, NVIDIA won't be able to use this infrastructure because it's GPL. Alan Cox replied on LKML to a request from one of their engineers to mark the API non-GPL: "NAK. This needs at the very least the approval of all rights holders for
the files concerned and all code exposed by this change. Also I'd note if you are trying to do this for the purpose of combining
it with proprietary code then you are still in my view as a (and the view
of many other) rights holder to the kernel likely to be in breach
of the GPL requirements for a derivative work. You may consider that
formal notification of my viewpoint. Your corporate legal team can
explain to you why the fact you are now aware of my view is important to
them."
The rest of the thread is worth a read (a guy from RedHat agrees that this code is GPL and cannot become non-GPL without relicensing from a major subset of graphics system contributors). This has a ripple effect: it means that all of the ARM SoC GPU drivers can't use it either, and it may prevent any proprietary drivers for the proposed DRI version 3.

Monday you had a chance to ask Linus Torvalds any question you wanted. We sent him a dozen of the highest rated and below you'll see what he has to say about computers, programming, books, and copyrights. He also talks about what he would have done differently with Linux if he had to do it all over again. Hint: it rhymes with nothing.

JamieKitson writes "The latest Webconverger 15 release is the first Linux distribution to be automagically updatable from a Github repository. The chroot of the OS is kept natively in git's format and fuse mounted with git-fs. Webconverger fulfills the Web kiosk use case, using Firefox and competes indirectly with Google Chrome OS. Chrome OS also has an autoupdate feature, however not as powerful, unified & transparent as when simply using git."

An anonymous reader writes "The Mesa developers released Mesa 9.0 with open-source OpenGL 3.1 driver support. This de facto OpenGL Linux implementation now supports the several year old OpenGL 3.1 specification for Intel hardware while the other drivers are still at OpenGL 3.0 or worse. Other features to Mesa 9.0 include completing MPEG1/MPEG2 video acceleration, early OpenCL support, bug-fixes, and new hardware support."
OpenGL 3.1 support is limited to Intel hardware, but at least ATI/AMD hardware supports some of OpenGL 3.1. A few features from OpenGL 4 were also added.

Linus Torvalds was (and still is) the primary force behind the development of the Linux kernel, and since you are reading Slashdot, you already knew that. Mr. Torvalds has agreed to answer any questions you may have about the direction of software, his thoughts on politics, winning the Millenial Technology Prize, or anything else. Ask as many questions as you'd like, but please keep them to one per post. We'll send the best to Linus, and post his answers when we get them back. Remember to keep an eye out for the rest of our upcoming special interviews this month.

sfcrazy writes "Samsung has created a new Linux file system called F2FS. Jaegeuk Kim of Samsung writes on the Linux Kernel Mailing List: F2FS is a new file system carefully designed for the NAND flash memory-based storage devices. We chose a log structure file system approach, but we tried to adapt it to the new form of storage. Also we remedy some known issues of the very old log structured file system, such as snowball effect of wandering tree and high cleaning overhead."

hypnosec writes with news that the Linux 3.7 kernel will support multiple ARM-based System on Chip platforms (Git commit page), writing "Up until now there has been a separate Linux kernel build for each of the ARM platforms or SoCs, which is one of the several problems when it comes to ARM based Linux. The merging of ARM multi-platform support into Linux 3.7 will put an end to this problem, enabling the new kernel to not only target multiple platforms but also be more in line with its x86 counterpart."
